Subject: [PATCH] x86, calgary: constify cal_chipset_ops structures
Date: Sat, 28 Nov 2015 16:58:15 +0100
Message-ID: <1448726295-10959-1-git-send-email-Julia.Lawall@lip6.fr> (raw)

The cal_chipset_ops structures are never modified, so declare them
as const.

Done with the help of Coccinelle.

Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr>
